Return root endpoint information.
AI agents call root to retrieve information from Blood Pressure Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply returns information about the root endpoint, analogous to a health check or API discovery call. It is purely a read/informational operation with no ability to modify, delete, or execute anything. Blast radius if misused is negligible.
From the tool's definition 'Return root endpoint information' — retrieves informational metadata about the API root endpoint with no side effects.

Attacks that exploit this kind of access
Return root endpoint information. It is categorised as a Read tool in the Blood Pressure Tool MCP Server, which means it retrieves data without modifying state.
Register the Blood Pressure Tool MCP server in PolicyLayer and add a rule for root: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Blood Pressure Tool. Nothing to install.
root is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the root rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for root. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
root is provided by the Blood Pressure Tool MCP server (mclarkson/bptool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
